Markup and Profit Margin Calculator

Enter your cost and a percentage to get the selling price. Switch between markup (on cost) and profit margin (on selling price).

Bookkeeping Formula Reference

Every formula used by these calculators. They match the FNSACC323 Perform financial calculations unit.

Tax
GST: Add
Price inc GST = Price ex GST × 1.1
e.g. $100 × 1.1 = $110
GST: Remove
Price ex GST = Price inc GST ÷ 1.1
e.g. $110 ÷ 1.1 = $100
GST: Find Amount
GST = Price inc GST ÷ 11
e.g. $110 ÷ 11 = $10
Business
Markup
Selling Price = Cost + (Markup% × Cost)
e.g. Cost $50, Markup 20% → SP = $50 + ($50 × 0.20) = $60
Profit Margin
Selling Price = Cost ÷ (1 − Margin%)
e.g. Cost $50, Margin 20% → SP = $50 ÷ 0.80 = $62.50
Sales Commission
Commission = Rate% × Total Sales
e.g. $10,000 sales at 5% → Commission = $500
Simple Interest
Simple Interest
Interest = Principal × Rate × Number of Periods (T)
I = P × R × T
e.g. $300 at 2% for 1 year → I = $300 × 0.02 × 1 = $6
Total Value / Total Repayable
Total = Principal + Interest
e.g. $300 + $6 = $306
Compound Interest
Future Value (Compound)
FV = PV × (1 + i/n)^(n×t)
PV = present value, i = annual rate, n = periods/year, t = years
Present Value
PV = FV × (1 + i/n)^(−n×t)
How much to invest now to reach a future target
Loan Repayment
Repayment = P × [rp × (1 + rp)^N] ÷ [(1 + rp)^N − 1]
rp = rate per period, N = total periods
Depreciation
Straight Line: No Residual
Depreciation = Total Cost ÷ Effective Life
e.g. $11,000 ÷ 5 yrs = $2,200 per year (same each year)
Straight Line: With Residual
Depreciation = (Total Cost − Residual) ÷ Effective Life
e.g. ($11,000 − $1,000) ÷ 5 = $2,000 per year
Diminishing Value: Rate
Rate % = 200% ÷ Effective Life
e.g. 200 ÷ 12 yrs = 16.67%
Diminishing Value: Depreciation
Depreciation = Rate % × Carrying Amount
Applied to the reducing book value each year, bigger early, smaller later

Break-Even Point

Units = Fixed Costs ÷ (Price − Variable Cost)

Fixed Costs stay the same no matter how much you sell (e.g. rent, insurance). Variable Cost is what it costs to make or deliver one single unit (materials, packaging, per-item shipping) — it goes up and down with sales, unlike fixed costs. Selling Price is what you charge per unit.

Markup vs profit margin

Both describe the same profit, measured against different things. Markup is profit as a percentage of cost. Margin is profit as a percentage of the selling price.

Markup: Selling Price = Cost + (Markup% × Cost)
Margin: Selling Price = Cost ÷ (1 − Margin%)

Example. An item costs $50.

At a 20% markup the price is $50 + $10 = $60.

At a 20% margin the price is $50 ÷ 0.80 = $62.50, because the $12.50 profit has to be 20% of the selling price.

Converting between the two

MarkupMargin
25%20%
50%33.3%
100%50%
200%66.7%
Margin = Markup ÷ (1 + Markup)  Markup = Margin ÷ (1 − Margin)

Mixing the two up is an easy way to underprice. If you need a 40% margin and apply a 40% markup instead, you end up with a margin of only 28.6%. There’s a longer walk-through in Markup vs margin: the difference, with examples.

Frequently asked questions

What is the difference between markup and margin?

Markup is profit divided by cost. Margin is profit divided by selling price. The same sale always has a higher markup percentage than margin percentage.

What markup gives a 50% margin?

A 100% markup. Doubling the cost means half the selling price is profit.

Can profit margin be 100% or more?

No. A margin of 100% would mean the item cost nothing. Markup has no upper limit.
